openwrt下如何添加wifi指示灯和wan指示灯？
我用的MT7620a的开发板，wled-->gpio#72，wan-->gpio#49,我在openwrt/target/linux/ramips/dts/MT7620a.dts里做了如下操作(红色部分)，可是编译出的固件指示灯还是不亮,各位大佬指导一下

以上是我的dts文件，代码部分为我增加的操作，最终不能实现功能，请各位大侠指导一下

可以在用户空间操作io吗？
/sys/class/gpio里可以看到，但是我需要怎么配置才能让wifi打开是指示灯亮，关闭WiFi时指示灯灭呢？
root@OpenWrt:/sys/class/gpio#
root@OpenWrt:/sys/class/gpio# ls
export gpiochip0 gpiochip40 gpiochip72 unexport

在/sys/class/leds/下也可以看到w856n:blue:wlan 我如下操作root@OpenWrt:/sys/devices/gpio-leds/leds/w856n:blue:wlan# echo "1" > ./brightness 也能点亮led,但是我要如何才能让WiFi开启时点亮，关闭时熄灭呢？
root@OpenWrt:/sys/class# cd leds/
root@OpenWrt:/sys/class/leds# ls
rt2800soc-phy0::assoc rt2800soc-phy0::radio
rt2800soc-phy0::quality w856n:blue:wlan
root@OpenWrt:/sys/class/leds# cd w856n\:blue\:wlan/

看看widora neo MT7688开发板的配置:
https://github.com/openwrt/openwrt/search?utf8=%E2%9C%93&q=widora%3Aorange%3Awifi&type=
有没有配置 /etc/diag.sh 文件:

我的/openwrt/target/linux/ramips/base-files/etc/diag.sh文件内容如下，这里面什么以上啊，我网上没找到资料，该如何修改配置呢？

在openwrt:/sys/class/leds/下可以看到7620a:blue:wifi
root@OpenWrt:/sys/class# cd leds/
root@OpenWrt:/sys/class/leds# ls
7620a:blue:wifi rt2800soc-phy0::quality
rt2800soc-phy0::assoc rt2800soc-phy0::radio
root@OpenWrt:/sys/class/leds#
我在代码中是不是应该在/openwrt/target/linux/ramips/base-files/etc/diag.sh这样添加啊？

我添加了gpio-leds在dts文件里，但是在sys/class/leds下面却没有生成对应的目录，请问是什么原因呢？
